same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, which form a part of this specification.

This invention relates more particularly to certain improvements in that class of pipevises illustrated by the vises shown and described in Patent No. 601,313 and Patent N o. 618,846, granted to George F. Condit in the years 1897 and 1898, respectively, the objects of the present improvements being to facilitate the operation of inserting 'the pipe into and removing it from the vise and to secure other advantages and results, some of which may be hereinafter referred to in connection with the description of the working p The invention consists in the improved ipe-vise and in the arrangements and cominations of arts of the same, all substantially as willp be. hereinafter set forth and finally embraced in the clauses of the claim.

Referrin to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several figures, Figure 1 is a front view of my improved ipe-vise. Fig. 2 is a section of the same, ta en at line Fig. 3 is a side view of said vise. Fig. 4 is a detail side view'lof a certain gripping-jaw and its carrier. Figs. 5 and 6 are etai sectional views showing the female parts for engaging the vise-screw and serving in facilitating the work of gripping and releasing the pipe. Fi s. 7 and 8 are sectional views illustrating t e -arrangement of a certain sectional nut and showing the screw 1n position. Fig. 9 is a detail plan of a certain collar, and Fig. 10 is a detail showing the parts engaging the pipe.

' In said drawings, 10 indicates the base of the frame of the machine, having oppositelyinclinedvbearings 11, forming a V-sha ed recess in which the pipe may rest, as in icated by the dotted outlines in Fig. 1. 12 indi- A the top cates the screw-carrying upper portion of the said frame, which is hinged or pivoted at 13 and fastened to the lower section by the latch or link 14 in any suitable manner, the said latch ior link Ibeingfladapted to release'said upper part to enable it to be turned upward or opened to permit the outpassage of the pipe with facility.

Between the downwardly-extending arms 15 15 ofthe upper portion, which provide vertical slideways4 16, is a carrier 17 for gripping-jaws 18 18, which latter are suspended from the said carrier by means of a suspensory pin 19, extending horizontally through a tubular extension 20 of said carrier. Said jaws project downward `:from bearings 21 on the under side of the carrier to the inclined bearings 11 and when in engagement with said inclined bearings are directed toward one another and into holding contact with the pipe as said jaws are forced downward. Said jaws are forced apart at their free ends as the same are raised from the pipe by means of springs 22, arranged in the said tubular extension on the horizontal rod 19, which projects oppositely from the ends of the tube into erforations at the upper ends of the jaws, t e said jaws being suspended from said rod and free to swing thereon to a limited extent of movement.

At the upper side of the carrier 17 is a socket adapted to receive the ball end of the screw 25, by means of which the carrier and its jaws 18 are forced into clamping relation to the pipe. Said screw is longitudinally grooved to enable said screw to be moved by a direct longitudinal movement toward and from the pipe, so as to quickly apply the jaws to said pipe and withdraw the same therefrom without the delay occasioned by the usual screwing and unscrewing process. With this end in view I form at the center of of the arching up er portion 12 a box-li e formation 26, w lch is interiorly threaded, as at 27, at its lower part to engage with the threads of the screw 25, and above'said threaded portion is recessed o1' chambered to receive a nut 28, the said nut being exteriorly threaded, as at 29, to enga e threads formed on the walls of the annu ar chamber or recess in the said box-like formation. The said nut 28 is also threaded interiorly to engage the screw 25. The continuity of the thread of the screw 25 is broken IOO by longitudinally grooving the'said screw, as indicated at 30 in Figs. 1 and7, and thefemale threads ..27 and the interior of the nut 28 are similarly groove-d and thus on the male member 25 four (more or less, if desired) threaded lon itudinal ribs are formed, and on the fema e members four corresponding vertical grooves are formed, and so when the vertical grooves of the box' formation and the vertiio cal grooves of the nut 28 are in correspond# ence, as inl Fig. 6, and the .longitudinal .threaded ribs are in coincidence-with the said corresponding .grooves then there willl be no intermeshing of the screw-threads and .the xg'screw :25 can be moved directly lengthwise; but by. turning thev nut a quarter-turn, more .or less, and thus bringing the vertical grooves of. theffemale nut to. ositions vertically out 4of'correspondence with the grooves of the zo box-like'formation, as indicated in Fig. 5, then. such longitudinal movement of the screwis prevented, and said screw may be turned effectively .by means of the handle 31 to forcethe jaws 18 into clamping relation to 25 the pipe. To hold the nut 28 in its position for screwing, .I Cpreferto employ a spring-latch 34, adapte' to slide vertically in a recess 35, formed vin the box-like formation 26 at one 3o side ofthe recess for the nut 28, said recess containing at its bottom a spring 36, on which the latch is seated and normally held inlits catching position to engage the nut. Said. latch is provided with a finger-piece 37, 35 byimeans of which it can be conveniently .gressed out of catching relation with thc nut. 1 aidenlargement 26 at a little distance from said'latch- 1s provided with an upwardly-pro- :jecting fixed pin 38, which serves to limit the 4o turning movement of the nut. Said nut 28 is provided with vlaterally-projecting lugs 39 .39, (shown more clearly in Figs. 5 and 6,) betweenwhich the fixedpin 38 extends, and .the movement of the nut is limited by said 4; .p1n38 to .an extent about equal to the space etween said lu s. When the nut is at the limit of'one of 1ts movements, the interior .grooves of said nut and the box-like formation are in coincidence, as in Fig. 6. When 5o at the limit of its reverse movement, said .grooves are out of coincidence, as in. Fig. 5, vseas to prevent a direct longitudinal movement of the screw 25. In this latter position the latch, forced' by the spring36, passes automatically into engagement with one of the lugs and locks the nut to prevent turning. The nut may be turned by hand by means of a finger-piece 40, projecting laterally out therefrom. I refer also to employ means 6o for automatica ly turning said nut, and to this end I employ a collar 41, which is held down upon the top face of the nut 28 with some considerable pressure by means of a spring 42, coiled around a reduced portion of'vsaid collar and bearing down on a flange 43 thereof. The upper end of said springs bears against the under side of a cap 44, secured to the nutand adapted to protect the spring. 'The reduced upper'end of the collar 41 extends between the cap 44 land screw 25,-

as shown in Fig. 8, and said collar is free to move up against the tension of the spring 42. On the under side of said collar are tapered projections 44, These are disposed on opposite sides oftheaxial center of the collar and project downward into recesses 45 of substantially'the same shape, formed in the u per side or face of the'nut 28, so as to cliitchtherewith. Onthe. interior walls of said collar 41 are ribs or keys 46, fitting within the grooves 30l of the screw 25, and thus the said collar is compelled to turn with the screw, but is free to slide lengthwise. of said screw. i

On turning the screw 25, by means of the handle 31, to release the jaws 18 from the pipe the collar 41 is immediately turned, and because of the relation of the inclined projections to the recessed nut the said collar is also turned to bring the grooves of the nut 28 and formation 26 into vertical coincidence, thus enabling the screw to be at once raised without continued turning. 0n reversing the movement of the handle 31 the collar throws the -nut back to the .position in which the grooves are out of coincidence, and on further turning the screw the projection 44a isl free to ride up the incline of the recess45, so that the screwing operation is not materially interfered with.

To bring the clutching-j aws 18 into proper clutching relation as well with small pipes as IOO with large, the teeth at and near the lower ends of the said jaws are disposed at the inner sides of said jaws, as shown in Fig. 10, where the three or four teeth near the eX- tremity of each jaw are formed in the segment of a circle, such as 50, while those farther away from said circle are arranged in a straight line 51 and thus in practice I am enabled to hold pipes of a great variety of sizes A securely .and with firmness.

The collar 41 and nut 28 may together be considered to be a sectional nut operating together to effect the results before detailed.

Having thus described the invention, what I claim as new is 1. .The improvedpressor clutch herein described, comprisingy means for supporting the parts to-be pressed or clutched, means for supporting. a nut, said nut disposed above .the first said supporting means, and a'screw arranged in said nut, said nut and screw being each vertically grooved and adapted to permit a direct vertical movement of said screw in the direction of the axis of said vscrew and threaded means forl closing thel grooves to enable the screw to be normally operated.

2.` In a clutch, the combination with the frame, screw and carrier operated by said IIS screw, and having an extension to receive -jaw operating springs, of clutching -jaws bearing underneath said carrier, a horizontal rod supporting said jaws and springs arranged on said rod and bearing oppositel)T on said jaws.

3. A. vise comprising a fixed jaw and a movable jaw, the fixed jaw having a screwthreaded perforation with longitudinal grooves, a screw-threaded bolt having longitudinal grooves therein, in the perforation of the fixed jaw, and a nut on the fixed jaw arranged to partially rotate thereon and having grooves arranged to be thrown in and out of register with the grooves in the fixed jaw.

4. A vise comprising a fixed jaw, a movable jaw, the fixed. jaw having a grooved screw-threaded perforation, a grooved screwthreaded bolt in the perforation to actuate the movable jaw, a nut rotatable on the fixed jaw and embracing the bolt, the said nut having grooves arranged to be thrown in and out of register with the grooves in the fixed jaw, and means to limit the rotation of the nut.

In testimony that I claim the foregoing I have hereunto set my hand this 13th dayr of May, 1905.
